RUBBER SHOE.

SPECIFICATION forming part of Letters Patent No. 404,264, dated May 28, 1889.

Application filed September 5,1887. Serial No. 248,821. (No model.)

To all whom it may concern:

Be it known that I, HENRY J. DOUGHTY, of Malden, county of Middlesex, and State of Massachusetts, have invented an Improvement in Rubber Shoes, of which the following description, in connection with the accompanying drawing, is a specification, like letters on the drawing representing like parts.

This invention has for its object the production of a novel rubber shoe or foot-covering, the same being seamless or in one piece, the line of junction of the material entering into the formation of the foot-covering being I 5 along the widest part thereof throughout its length.

My invention consists in a shoe or footcovering composed of two parts, the line of junction of the material constituting the said shoe or foot-covering being along the widest portion thereof through out its length, the said line of junction from the ball to the rearmost extremity of the shoe or foot-coverin g passing through the upper between the sole and the z 5 mouth of the shoe, as will be herein fully described.

The drawing in side elevation represents a shoe or foot-covering embodying my invention, the heel being partially broken out to 0 better show its construction.

In an application, Serial No. 248,822, filed on the 5th day of September, 1887, I have shown and described an apparatus for the manufacture of the shoe or footcovering 5 forming the subject of this invention. The

said application shows a stationary mold surrounded by a steam-chest, a movable mold, and co-operatin g steam-chest surrounding it, being pivoted or jointed to the stationary o steam-chest by a hollow hinge adapted to permit the circulation of steam from the stationary to the movable steam-chest, and vice versa, whether the mold be opened or closed, so that the heat is kept constant in the molds, to thus 5 facilitate the vulcanizing operation. These two molds have co-operating with them a last or inside former, of metal, the said last being adapted to be depressed into the countersunk space of the stationary mold and upon the rubber or other material previously laid in the said stationary mold. The material laid in the stationary mold constitutes the top portion, a a, of the shoe or foot-covering.

The last or inside former having been drawn down upon the material within the 5 5 stationary mold, a second quantity of rubber or equivalent material is laid upon the top of the last, the latter being inverted with the sole uppermost, and thereafter the movable mold is forced down upon the said material, pressing the same closely upon the bottom of the last and lapping it over upon the body'of the last along the shank and about the heel of the last, the material so laid upon the last and receiving upon it the movable mold being shaped to form not only the sole 1), but also a portion, 1), of the top of the shoe or foot-covering below the line 8 8, and also the heel N.

The line 8 8 constitutes the broadest part of the shoe or foot-covering, and it is along this line that the two layers or pieces of material applied to the stationary mold and to the last or inside former are joined.

From the foregoing it will be seen that the material entering into the formation of my improved seamless shoe or foot-covering is so applied in the mold and to the last or former that that portion of the shoe or foot-covering marked a, it constituting the chief part of So what may be called the upper, is joined to the portion marked 6 b b constituting not only the sole and heel of the shoe or footcovering, but also a flanged portion,which is extended about the heel end of the sole and united with the portion a along the line 8.

I claim- As an improved article of manufacture, a rubber shoe or foot-covering comprising, essentially, two sections or portionsviz., an upper portion, as a, and a portion molded or shaped to constitute not only the sole and heel portion, but also to leave a flange-like portion extended upwardly from the sole from the ball of the shoe backwardly along the shank and heelthe two portions or parts being permanently united together in the widest part of the shoe between the toe and heel thereof, substantially as shown and described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

HENRY J. DOUGHTY.
